(a) The equipment shown in the diagram was used by a student to investigate the variation with volume, of the pressure p of air, at constant temperature. The air was trapped in a tube of constant cross-sectional area above a column of oil. scale air- H pressure gauge oil- to air pump valve The pump forces oil to move up the tube decreasing the volume of the trapped air. The student measured the height H of the air column and the corresponding air pressure p. After each reduction in the volume the student waited for some time before measuring the pressure. Outline why this was necessary.

A soccer referee inflates a soccer ball to the standard required measured pressure for a game of 90kPa, before the game. The balloon has an internal volume of 2650 cm3 and the air is at a temperature of 25°C when the balloon is first inflated. The ball is brought onto the field of play, and by the time the game starts, the air temperature has dropped to 0°C. Assuming that the volume of the ball does not change significantly, determine the following: a. The amount of heat transferred from the air to the ball during the process.b. The initial pressure to which the balloon must be inflated so that it is at the required measured pressure of 90kPa when it reaches a temperature of 0°C.
